Charge 6 or Something else

I probably need some Suggestion and opinions. I've Just ordered and tested an inspire 3 but unfortunately especially for swimming, the watch was very inaccurate. In fact, I swam about 26 laps of 50 meters each. That’s what I had set it to. But in the end, the watch showed 44 laps, yet only about 200 meters. Since I bought it mainly for swimming, I’ve decided to send it back for that reason. It’s no use to me if my fitness tracker doesn’t track properly.

Now I’m wondering if it’s worth buying the Charge 6 instead. Do any of you have experience with it and can you recommend one?
